Scott, this is good.  I did find a small typo "say what they are and ask *hir* to check for you" under the Complete Description heading.  Also, a suggestion: Can you link to photos of what you are describing (like catalog number inside dj, number on spine, what a buckram looks like, etc.) and also link to pertinant info on dogeared.  I've seen several auctions on ebay that describe a type 8 as buckram.
I've added seven new FAQs, all dealing with eBay.  tossed out three potential additions as redundant.) Please check 'em out and send your suggestions for additions or changes. What's missing? What's incorrect?
